The Missoula County Sheriff's Office spokesperson Brenda Bassett says there's a public safety risk for Arlee and the surrounding area as law enforcement officers search for a shooting suspect after two separate but related incidents that started late Thursday night. Bassett confirmed just before 3 a.m. the second incident was an officer-involved shooting, but the extent of injuries, if any, is unclear.

Lake County Sheriff Don Bell confirms Highway 93 North four miles past the Wye is shut down as authorities are actively looking for that suspect in the Arlee area. Sheriff Bell says they are searching for a white Chevrolet Suburban.

Lake County is assisting Missoula County and the Montana Highway Patrol after a series of events that started on Expressway in Missoula just before 11 p.m. Thursday. A Missoula police officer confirmed a shooting happened near Lithia dealership. Police say two people went to the hospital with gunshot wounds after a fight started between them and the occupant(s) of a white Chevy Suburban. The Suburban left the scene. We don't know the extent of the victims' injuries.

Just after the reports of shots fired, NBC Montana confirmed Providence St. Patrick Hospital in Missoula locked down. In a release, a hospital spokesperson says they locked down at 11:41 p.m. because of warnings of a public safety risk.

In a statement, James McKay, M.D., Chief Physician Executive – Acute Care said, “After receiving the public safety message, the hospital went into lockdown out of an abundance of caution for our patients and caregivers. Staff monitored the incident, and by communicating with the Missoula County officials, determined there was no known immediate threat, and lifted the lockdown at 1:43 a.m. No patients were affected, and patient care was not impacted as a result of the lockdown.”

Around midnight, police received reports of another shooting at the Evaro Bar involving an officer.

Law enforcement officials are not commenting on injuries or the amount of victims from the Evaro shooting at this time. Again, they are actively searching for a suspect in the Arlee area, but urge everyone in Missoula and Lake Counties to lock your doors and stay vigilant.

We have several reporters on scene. Stay with NBC Montana as we continue to follow this developing story.
